Sorta. (Android is technically Linux) What you would want to look into is a custom Android ROM. Something like OmniROM or ArrowOS.
As a side note though, installing can be a bit technical for some people and some apps don’t like to work outside of the “security” of a factory version of Android. If you are interested, I would browse around the custom Android communities here (if there are any yet) and check out sites like https://www.xda-developers.com/
No, there are unfortunately no truly workable Linux OSs for phones yet AFAIK. But there are plenty of Android-based OSs that work really well, and are usually maintained for quite a while, depending on the popularity of your device. Look into LineageOS, or Pixel Experience, to name a few.
Like Linux? I don’t know anything about it. I’d definitely try.

Is that where you have to root it and sideload the OS? I’ve read about it.
Yeah
Also mention lineage OS, Graphene OS and Calyx OS too

There’s ubuntu touch. I’m not sure how many phones that works on though.
