No.

Database namespaces are not supported.

However, you can write a datapump tool, or use an existing one, to
connect to the two databases simultaneously and stream the output of
a query on a table in one database as parameterised inserts into the
corresponding table in the other, in a single (cross-database)
transaction. There are several such tools around.
