It depends on how you have partitioned it - assuming you want to move
the existing partitions. 

Otherwise it is no issue at all;  grub indexes by device and partition,
so it does not care if the boot partition is on the first or the seventy
first device. *But* you do have to load the boot-loader, grub, somehow.
How that works can depend upon your firmware - sometimes you can only
boot from the 'first' drive although I'd guess that any reasonably
decent modern firmware won't have any problems.

In openSUSE Yast will allow you to configure and reinsert the GRUB/GRUB2
boot loader.
