I just want to know if it’s safe to have two databases that are relational to one another, rather then the tables inside the database being relational to one another? (don’t get me wrong the tables will still be relational)

The actual relations are usually enforced by the application that is using the database. So if you have a relation that goes from database A to database B, then you can just implement it like that in your application.
Of course by having two different databases, you can’t get the internal support for relations you usually get from the database system. So for example you can’t specify foreign keys and add rules based on them.
