Can sperm cells penetrate the cell membrane of non-ovum cells?
It is very possible that the specific enzymes that penetrate the cells can be used to lyse other cells or at least manipulate the plasma membrane. That being said, I don't think that sperm cells can be used to do that because the acrosomal reactions that you discuss are only activated by the presence of the zona pelliculada of the egg cell. Since that doesn't exist in any other type of cell a sperm cell can't be used for Acrosomal enzyme delivery for somatic cells, for example.
If you want to read more, the Wikipedia page about the Acrosome reaction is pretty good.
