Probably, your answer is "no".  From RFC 2131:

"If no address is available, the server may choose to report the
problem to the system administrator."

So, best guess ... when asked, your server replies "sorry" and
the wireless clients go on looking.  But I'm not familiar enough
with DHCP client behavior to know *for sure*.  Seems likely,
though, from my experience w/clients.  Surely anything else
would violate POLA....

Should be possible to muck around in /etc/syslog.conf and quiet
the daemon down, though.
