I run Ubuntu out-of-the-box on a ThinkPad Yoga X1 and everything works pretty well, including the docking station, the digitizer, touch screen, hotkeys, battery life. Same was true with my older Thinkpad T420 (which had Nvidia Optimus). The good hardware combined with the good drivers is the reason why I did not yet switch to Mac.
