Maybe I was lucky, but I never had any serious problems in Linux with any of the many Dell, HP and Lenovo laptops that I have used during the last 2 decades.
The most serious problem that I had was about 10 years ago in a Lenovo laptop with NVIDIA Optimus (i.e. where the NVIDIA GPU does not have direct video outputs, but it must pass through the Intel GPU). At that time, I spent a couple of days until succeeding to make NVIDIA Optimus work OK in Linux. With the Intel GPU, Linux worked fine since the beginning. This happened because at that time the Linux NVIDIA driver did not support Optimus, so you had to install a separate program to be able to select which GPU shall be used by an application. I do not know if any laptops with Optimus still exist today.
Except for that case, I never encountered any hardware compatibility problem that could not be solved in minutes or a few hours of most. For contrast, with Windows I have seen many problems that could not be solved in weeks, even with the assistance of IT support personnel from multiple continents, because nobody, not even the "professionals", had any idea about what Windows is really doing and what may be wrong.
It is true that some of the laptops that I have used had a few features that I have never used, so I do not know if they worked in Linux. For instance I have never used a fingerprint reader or a NFC reader.
