There are still components that you need to watch out for when buying a used laptop if one intends to run Linux. Broadcom WiFi is notoriously painful for example (have seen routine updates break those drivers several times over the years), and even though Nvidia provides official Linux drivers those can complicate things too.

The most painless Linux laptops are those that use integrated graphics only and for the best experience, use Intel networking instead of Realtek (Realtek often works, but it working well is highly dependent on the specific chipset).
