If 10.0.0.1 is the IP of the local host on the LAN, it shouldn't matter at all. The OS will realize the IP address is assigned to the local NIC and won't send any packets across the wire. The only reason it might be a problem would be if your firewall is configured to block incoming DNS requests from your LAN, but in that case you would realize the mistake immediately because no DNS queries would ever succeed. :)
