I’m sure some releases have become unsupported. The nature of Linux distros makes it a bit harder to define exactly which ones, even harder is you consider flatpak and snaps.
I would be surprised if any of the big ones released at the time Windows 7 was released is not supported. If course there’s no gatekeeping on the upgrades that I’m aware of (in general at least)
