It all depends on whether you have any Unix dhcp clients in the AD 
domain, because these will not update their records in AD.

Windows clients can update their AD records.

Your domain clients must use the DC(s) as their nameserver(s) and 
anything it doesn't know about (www.google.com for instance) will be 
forwarded to the DNS server set in smb.conf or the bind conf files (if 
using Bind9).

So, yes you can use your dnsmasq server, provided it isn't in the same 
dns domain as your DC(s).
