On the auth server: this will be fine. Many servers host a domain and 
its sub-domains: this is normal practice.

On the recursor: you just need a single forwarding rule for 
10.in-addr.arpa.  You can make this change first if you like.  If 
someone tries to resolve a subdomain that doesn't exist like 
42.10.in-addr.arpa before you've made the auth server authoritative for 
the whole of 10.in-addr.arpa then it will respond with REFUSED, which 
will be seen as a failure by clients. But you can add an empty 
10.in-addr.arpa zone and then it will become NXDOMAIN.  And then migrate 
your records.
