No, see Policy §2.2.1:

,----
| In addition, the packages in *main*
| 
| * must not require or recommend a package outside of *main* for
|   compilation or execution (thus, the package must not declare a "Pre-
|   Depends", "Depends", "Recommends", "Build-Depends", "Build-Depends-
|   Indep", or "Build-Depends-Arch" relationship on a non-*main* package
|   unless that package is only listed as a non-default alternative for
|   a package in *main*),
