From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You can use about any laptop with Linux. I would say take a current laptop and boot into a distro using a live usb. This will let you try it without installing it. You do occasionally run into issues with some hardware: fingerprint, wifi, trackpad, etc. So this is a good test.
But otherwise if you want a laptop that guarantees Linux support: Framework, System76, Tuxedo
