No, whois reports the registrar that manages the domain, the DNS is irrelevant. For example: http://whois.domaintools.com/citricsquid.com switch to "Registration" profile, "ICANN Registrar:GODADDY.COM, INC."
The one flaw with this is that it takes "up to" 7 days to transfer depending on the registrars in question. I moved a domain to godaddy 4 days ago and it still doesn't show that it's with Godaddy.
edit: Nevermind, you meant in this specific case where it's using DNS. You're right, although it can be done via the whois data.
