Yes. But once you've done that, nothing will be able to read the file.

You can copy the data/tables from to your primary mdf file.

How? That depends on your current configuration.
If you post your databases DDL (create database statement) we may be able to point you a route.

For same DB and same filegroup, you can DBCC SHRINKFILE with EMPTYFILE option, then drop the empty data file.

If you're going to recommend such a thing, then you also need to identify all the nasty stuff that happens along with that recommendation.

Yes you can merge two or more database to one by restoring the databases which you want to merge and another way is to use third-party SQL Recovery Software, which is easy and fast solution that will help you in merging the two different SQL MDF file databases.

How does restoring databases facilitate their merge?
I do not see anywhere on the SQL Recovery Software site which talks about merging databases.
