What would be the possible consequence of concealing an incomplete degree?
I wrote about this here.  

Short answer: yes, it is considered dishonest, and the possible consequences are severe.  You could be dismissed from your new program, or, if it's discovered after you finish, have your degree revoked.  The likelihood of this actually happening is hard to evaluate, but those sorts of sanctions will certainly be "on the books" and available if the school decides to enforce them.  

You'll be much better off if you submit the transcript and explain in your application why you decided to drop.
