On paper yes in practice not so much.

The officially listed "qualified" combinations are not strict (and hard)
requirement-combinations; as long as the CUDA dkms compiles for your kernel
and the nvcc works with the gcc compiler you provide it, things will
generally work. Kernels or compilers shipped by a distro can deviate enough
from others that issues may arise, but those cases are not overly common
(as far as I know, though admittedly I don't maintain diverse
infrastructure).

By the way, your distro is not "qualified" at all ;)
