For context (in case anyone thinks I'm nitpicking and all laptops are horribly supported on Linux): Basically everything works on the Thinkpad X1 Carbon [2], even the latest model (Gen11) as long as you buy the right one (no MIPI webcam).
Unfortunately, Lenovo refuses to put AMD processors in X-series thinkpads (its top-of-the-line laptops).
