At some point, it will come out. It's not a question of if but rather of when. But the point isn't whether you could get away with it.
Just because you can doesn't mean you should.
If you feel compelled to apply out, do it through the proper channels and build a strong app with letters of rec, official transcripts, and as a student in good standing with your current institution.
