I had a very old HP laptop.
I installed Ubuntu 20.04, no problems.
Laptop board died. I bought a mini pc, different CPU and GPU. I moved Ubunuty SSD from HP laptop to mini pc as it was, and it worked. Without doing anything all was running: wifi, gpu, bluetooth (even better than corporate Win11 laptop).
I run Steam and I was playing just like before my old games.
Magic.
