It's not that peculiar if you assume all countries follow the same type of happiness distribution that is simply shifted/stretched lower or higher.
Then, the relative size of a bottom or top absolute threshold is highly meaningful. Even if it's a fraction of a percent, populations are huge and suicide rates are not rounding errors at all -- they're actually quite statistically significant.
And as macabre as it is, suicides are objective facts mostly unaffected by methodology, and unaffected by translation issues, cultural differences, etc.
This is why suicide rates are actually a powerful mental health statistic, just like height is a powerful physical health statistic, at the population level. There's obviously still a lot both of these metrics don't say, but the fact that they are highly objective makes them extremely valuable.
"The large variations in the systems and processes to define mortality causes imply there may be very different numbers of deaths that are registered with a specific cause. This creates a problem for cross-country comparisons of mortality by cause in general, and even more so for deaths of despair, and suicides in particular.
The person responsible for writing the cause of death on the death certificate may be different across countries. In some countries, the police are responsible, while in others a medical doctor, coroner, or judicial investigator takes on this role. Differences in doctors’ training, access to medical records, and autopsy requirements contribute to these discrepancies. The legal or judicial systems that decide causes of death also vary. For instance, in some countries suicide is illegal and is not listed as a classifiable cause of death, leading to underreporting or misclassification of suicides as accidents, violence, or deaths of “undetermined intent.”[25]
Data on suicides, even when reported, can be inaccurate due to social factors as well. In some countries, suicide might be taboo and highly stigmatised, so the families and friends of the person who committed suicide might decide to misreport or not disclose the mortality cause, causing underreporting of its incidence. In other societies, such as Northern Europe, there is less stigma attached to suicides, and alcohol and drug use."
I don't think it would be that difficult to reconcile suicides between G20 countries. Outside of that, sure, data collection methods and quality heavily differ. But many people are interested in the varying levels of happiness among the G20 and there it doesn't seem that difficult to compare.

I wouldn't be surprised if cultural differences are actually the largest factor that explains a country's suicide rate. Not easy to prove, of course, but I would be very careful drawing any conclusions from differences in suicide rates between countries with vastly different cultures.
I think you can also expect large differences in how countries report their suicide rates.
I won't go into too much details on the topic, as it's loaded with triggering elements. Let's just say that if you were to study how different cultures apprehend and conceptualize life and death (whether philosophically or religiously), I'm fairly sure that you'd come out the other end questioning a lot of your original assumptions (which I only presume you hold based on your comment). Our collective outlook can have significant and far reaching influence in individual decisions.
> if you assume all countries follow the same type of happiness distribution that is simply shifted/stretched lower or higher.
That's a pretty strong assumption, seems more likely that there's variation at the extremes than not. For example, if a small percentage of the population deals badly with extended nighttime in long winters, then it'll affect Finland's most-unhappy stats (and suicide rates) without meaning much for the average happiness.
Most Asian cultures with suicide problems acknowledge and try very hard to bring those rates down. It isn't just a cultural norm and is in fact a good indicator of the happiness of a population.
Here's [1] the Japanese Ministry of Health, Labor, and Welfare's page on preventing suicides. The motto is 誰も自殺に追い込まれることのない社会の実現を目指して or "Aiming for a world where nobody must deal with suicide"
That's a straw man; There are many cultures that have a strong emphasis on honor/shame mechanics, which in turn drive suicides in those cultures. And which match cultural expectations in a grim kind of way.
The fact that people want to change their culture is possibly an early indication of a shift, which could take decades or centuries to actually occur. And such a cultural shift can also lose momentum and be still-born.

I find counting suicides innovative. But if you do it in a global context without looking at the cultures as confounding factor: It's wrong.
There are many other confounding factors, such as a forgiving national (personal) bankruptcy regime. The USA has a pretty forgiving regime compared to other countries. But that doesn't mean you can say it correlates with how happy people are. Because - like suicides - the number of people that go bankrupt might not significantly correlate to the average happiness rate. Because a (small) minority of people go bankrupt / commit suicide.
It's in fact perfectly reasonable and possible to suppose that a country with higher average suicides and harsher penalties for bankruptcy still ends up higher on the happiness index. Because perhaps health and social-contact / family factors impact the rating more, on average.
Then, the relative size of a bottom or top absolute threshold is highly meaningful. Even if it's a fraction of a percent, populations are huge and suicide rates are not rounding errors at all -- they're actually quite statistically significant.
