Untested but your solution will be something like this:

function verifed_profile_check( ) {

     $user = get_userdata( bp_displayed_user_id() );

     if ( in_array( 'certified_subscribers', (array) $user->roles ) ) {

         echo '<span class="pmpro_label"> CERTIFIED PROFILE </span>';

     }

}
