I’ve installed this on an old Chromebook already and it does work. You have to dig around for it a bit online but it has been available publicly for a while.

However , surprise, if it’s an old Chromebook you’re going to have to remove the internal write protect screw or use a Susie-q cable to make it the primary operating system on the device as they never intended for you to overwrite the existing os.

You can boot from usb or dual boot though.
