Yes, you can. Dextromethorphan (DXM) can cause a trip. However, certain other active ingredients in the medicine can be dangerous. i.e. phenylephrine.

Check erowid.com for more info.

Actually, NyQuil has phenylephrine. DayQuil does not. Though, cough syrup is a stupid way to trip regardless of adulterants. Man up and buy real drugs.
