Yes, you can, please follow and read the link in your message:

I guess you are doing this using either:
- mask: which you should not use, since it is obsolete and will be
removed at some point,
- embedded boundaries
In either case your domain is still square or cubic but some parts are
masked out, which is not the same as the non-square/cubic domains the
documentation is talking about.
