Well, yes and no.. technically, the PDGA actually tried par 2 holes at the 2001-2002 Worlds, if my source is correct. The eventual verdict was that par 2 holes were not received well, resulting in the guideline that any hole that based on length (rather than intended number of drives before reaching putting range) *should* be a par 2 should instead be redesigned. So there *can* be holes that are too short and easy to be a par 3 for the intended difficulty (i.e. red, white, blue, gold), which in this respect *could* be called par 2.. but really the ultimate answer is no, there's (currently) no such thing as a par 2 hole, there's just poorly designed par 3 holes that fail to produce the desired score distribution, and thus need redesigning.
For reference, you can see from the PDGA par guidelines that par 2 holes (marked in pink) are indeed on there.. with the recommendation to not use them:
