Yes, I do this with puzzling.org
It has subdomains imaginary and poetry, soon to have nomic. Even the
standard www.whatever.com is a vanilla subdomain.
Think of it as having bought a whole domain tree -
In fact, I am using register.com as my DNS server and there is a record
for any address of the form *.puzzling.org that isn't specifically listed
(I don't know how to do this in BIND, I use djbdns, and only internally).
You can do all kinds of things you.can.do.this.com, or you can have a mail
record for mail.here.com, but not have a A record for it, or have several
names pointing at a single IP address (very common).
You could also hand over subdomain.whatever.com to someone else by telling
your DNS servers to refer requests about subdomain.whatever.com to their
DNS server and then they could create subdomains of
subdomain.whatever.com... this continues up to a certain character limit.
