There's nothing special about any level of the DNS hierarchy.

Maybe what you mean is that the second-level domain is the name of the
zone. Since a zone has to have SOA and NS records, and DNS rules
prohibit a CNAME record from having other records of its own, it's not
possible to use the zone name as a CNAME.
