Certainly.  See `man dhclient.conf`.  You just need a "request"
statement that asks for all the default options _except_
domain-name-servers.  On my own system I'm running BIND, so
my dhclient.conf contains a line:

      prepend domain-name-servers 127.0.0.1;

That way, as long as my local server is running it will handle
any DNS requests.  If it fails, then the server(s) returned by
DHCP get used.
