Running GNU/Linux on a tablet, as of November 2018

There seems to be little information available about what distributions are able to operate tablets (tablet-computers). I'm specifically addressing 7in-10in "true" tablets, _not_ hybrid laptops with touchscreen and detachable keyboard. I've searched the web for several days (including this very site). I found much information, but: - all of it is either obsolete, or so old that it's probably not relevant anymore. Example: the Ubuntu wiki still has pages about Ubuntu Touch, which has been abandoned by Canonical; I went to https://ubuntu-touch.io and https://ubports.com , but all pages are missing a date, and the FAQ refers to "16.04" as a future release whereas it seems to be released already. - I found contradicting evidence: some people say tablets are closer to smartphones than to laptops, especially as regards proprietary drivers for the tablet peripherals; others say that x86-powered tablets can run GNU/Linux just like laptops do. As an example I've skimmed through the openSUSE website and couldn't determine whether the current version is installable on a tablet, or under what conditions (regarding the tablet hardware). Ubuntu Touch promotes only 4 devices, among which only one is a tablet! (The other 3 are smartphones.) All this leads me to the conclusion that running GNU/Linux on a tablet is, at the time of this writing, either very delicate (but then, why so few up-to-date questions or pages on this subject?) or very straightforward (but then, why no mention at all of such an install on e.g. the openSUSE website?). I couldn't even find a relevant tag here. "tablet" refers to graphical tablets (digitizers), "tablet computer" didn't exist until I used it, "smartphone" isn't really relevant, "phablet" & "hybrid computer" wouldn't be if they existed... So the question is: can you point to GNU/Linux distributions that explicitly support (some) tablets? A link to an _up-to-date_ page stating the given distribution generally supports tablets, or listing supported models? (Something like https://wiki.ubuntu.com/Touch/Devices/Nexus , which is now both obsolete because Ubuntu doesn't support Touch anymore and outdated because the last tests date back to more than 4 years...)
