No, you have to use backup controlfile in this case.

For incomplete recovery you can use the current controlfile only if there has been no changes in the physycal database structure between the time you are performing PIT recovery to and present. In your case, the database structure must not have been changed between t+1 and now if you want to use current controlfile.
