Absolutely. Just to add to your examples of why soluicide is systematically under-reported in certain countries, in many Eastern Orthodox countries (Eastern Europe, Russia, Greece), suicide is considered a mortal sin and victims of suicide are denied burial in religious cemeteries (and denied normal religious burial rights) by the church.
Not only that, but in Russia you may be slapped with the fine for the 'propaganda of suicide' (I shit you not it's the real law) if you even discuss suicide on more or less popular platform.
