No.
 

Technically, the answer is 'yes' to the question asked.

 
You want

because declarations in the outer module have no meaning on
interfaces.

This is the answer to the question you meant to ask.  An interface
construct introduces a new namespace and blocks host association.
As such, Fortran's implicit typing rules apply
