Aren't we talking about a server that's authoritative for both domain.com
and sub.domain.com?  The delegation from COM will point to this server, and
when you ask it for something in sub.domain.com it will answer, since it's
authoritative for the subdomain.  The lack of delegation NS records in the
domain.com zone will never be noticed.
