You can copy the kernel and module files into different systems, e.g. copy Arch
kernel (/boot/vmlinuz-*, System.map-*) and modules (/lib/modules/*) into Leap
system.  Recreate initrd (run mkinitrd once), and run "grub2-mkconfig -o
/boot/grub2/grub.cfg", and you'll be able to boot it.

Vice versa, copying openSUSE kernel to Arch system should work similarly.

If Arch kernel on Leap shows working, we can try to see the exact difference.
