Yes, you can create a Match block with the criteria User, something like 
this I guess will work (haven't tested):

PermitRootLogin yes
Match User root
     PasswordAuthentication no

check the man page. You might also want to restrict from where root can 
login with another match block.

I assume that you have decided root login is acceptable with the 
increased security of key authentication. Just beware that the key must 
be password protected.
