I've definitely ran older kernels of Linux on new Intel/AMD CPUs where the kernel release vastly pre-date the CPU release.
I've found that doing this on laptops is often more problematic, the OS itself will usually boot fine, but you might have issues with drivers for supporting hardware like the GPU, audio, etc.
