The hard part is figuring out whether stuff like keyboard backlight will work. Even for popular developer models like the pixelbook, you google around and find two or three conflicting reddit posts that tell you it doesn't work but there's a fix in this link to a tweet that's been deleted.
Does audio work? Does the headphone jack work? Does headphone jack auto sense work?
I use MrChromebox firmware on a Pixelbook (Eve) and many things work fine, like Wi-Fi, suspend, brightness, and keyboard backlight. Annoyingly, audio doesn't work. I can't remember whether camera/microphone work.
I've run linux (debian and arch) on several chromebooks over the years using MrChromebox and I've never been able to get working audio. I've never had issues other that audio though.
