No, you cannot service the joint between the tank and the bowl. And because it is hidden, it could leak for decades creating mold without anyone knowing until people get sick from black mold.
I have never seen or heard anything about that. Over here 95% of the crappers are wall mount with a hidden - whatever Spülkasten is called in English. The water reservoir with all the mechanics inside. What does frequently happen: If you got freshwater with a lot of minerals the flush mechanism can get stuck after 5 years or so. Therefore I open up mine once a year or so (no tools needed) and add some acid to decalcify stuff.
They got common in the late 80s / early 90s, before a very weird kind of crappers were common here which I can just call poop inspection crappers. Poop landed on a kind of “dry plate” and flushing would flush it off. You needed to brush more with a toilet brush, the advantage was no splashback. Those typically were floor. mount.
