Yes, you can.
However, the separation between databases is stronger.
For example, some people take offence if others can see their metadata.

My recommendation is to use different databases whenever you are
dealing with distinct data sets and different applications.
But if you have data sets that you routinely need to join,
it is better to have them in a single database.
