But it's a space where more expensive older hardware might still be worth it. E.g. my full piano size 24 year old Yamaha w/velocity sensitive keys and pedals still works flawlessly and the current version of it is still expensive new (at least from the point of view of a casual user...)

It's now connected via a cheap USB adapter to my Chromebook (biggest issue: latency of the - mostly Android - apps) planning to connect it to my Linux box instead.

Honest question, is there any possibility of easily installing Linux on a Chromebook?

You can always install Linux on any Chromebook, or install a Linux VM (but that may not make it trivial to directly attach devices). To the best of my knowledge 100% of Chromebooks are fully supported.

No idea, I suspect that will very much depend on the manufacturer. I've never looked into it.
