Linux generally doesn't have any issue with swapping anything. I've transferred the same SSD between Intel / AMD. Radeon & AMD > Nvidia. The only possible issue is if you installed non repository drivers. Outside of that though it will be damn near transparent to the system.

I am using currently the open source AMD drivers already included in the latest Linux kernels. Unlike years ago they're stable even with pre RDNA cards (but I just tested with HD6000 cards I didn't test the HD2000, HD3000 and HD5000 cards yet). I used previously the old Catalyst propietary drivers that gave more 3D performance but after the recent clean install I just left the open source ones. The propietary drivers were a real pain to install and to update.

I will try just switching the videocards then. Thank you.

As long as you're not trying to use the old Catalyst drivers, and an ancient kernel, you should have no issues just swapping GPUs. My current Arch install is about 8-9 years old, and it has had dozens of different GPUs (both AMD and NVIDIA), and 4 different CPUs.
