No: if the server asks for an address over DHCP, your router will answer
with the specific address you configured.

Not really.  It will make your network more robust in the unlikely event
that the server boots when your router is down (and thus not giving out
DHCP addresses).  On the downside, now there are two paces to configure
the server's IP address: on the server _and_ on the router.  Then again
why would you want to change the server's IP?
