I don't think so either, because:

1. Karai said in 'Enemy of My Enemy' that if Leonardo wanted a feud he has one.

2. If Shredder ever found out about a friendship between those two, he would be beyond mad.

3.She's going to have to pick a side sometimw, and she'll probably choose Shredder.

But there is possibility that Karai really is Miwa ( which I'm hoping she really is :D ) and she goes over to the good side and restarts her friendship with Leo.
