Do I need a linked server if both databases reside within the same SQL Named Instance?

DatabaseA needs to be able to retrieve data from DatabaseB on a periodic basis. Both databases reside on the same instance (SERVER\INSTANCE).

If they exist on the same instance no, use cross database queries

Like the following.

INSERT INTO DatabaseA.dbo.Mytable SELECT Col1, Col2 FROM DatabaseB.dbo.MyTable

If the database was on a different server, then yes a linked server would be needed.
