Kind of.

Wildcards are carried in AXFR so that primary and secondary name servers
both know to synthesise the required records.

It is technically possible to explicitly ask for `*.example.com` to test
for the presence of a wildcard, but otherwise the synthesis is done
entirely on the server side and the `*` does *not* usually appear in the
DNS wire protocol.
