Yup, happens all the time:
example.com:
www.example.com. 600 IN A 192.0.2.1
example.net:
www.example.net. 600 IN A 192.0.2.1
foo:
www.foo.com. 600 IN A 192.0.2.1

That all depends on how you are trying to use it -- when an application looks up the label it is presumably going to so something like connect to it, and the server is going to have to know how to respond.
For example, if this is a web-server it will need to have virtual hosts configured to is can respond as example.com / example.net / foo.com, etc.
If a mail server, it will need to know what all domains it handles mail for (aliases file, etc)
