In my opinion, the most important thing is hardware compatibility. It is much better today than it was 10 years ago, but there are still laptops or parts available, that do not have linux-support available.
This is also true for laptops that are sold as "linux compatible" (but much less likely).
I have already seen the exact same models, which one of worked and the other was without WiFi, just because it had another WiFi chip.
So I really can't give any advice, but I have to say, just try it.
