Are they doing anything to prevent Linux from running well on them? As far as I can tell, since all big three (XPS, EliteBook and Thinkpad) are considered enterprise devices and their BIOS, IO tables and hardware layouts are crafted with Linux compatibility in mind.

They're explicitly sold with FreeDOS option to imply that you can directly install Linux on them.

Even my run on off the mill desktop shows more soft-errors about IO layout and memory mapped devices on board.
