Android - Can I force move to sd card applications that don't want to be moved there?

Yes, you can move any apps that don't normally allow it, including system apps, if you have root. Note that most apps that doesn't allow moving usually do not allow it for a good reason, so if you force move you may get crashes and other stability issues. You need an app2sd application that uses root, like this: https://market.android.com/details?id=com.droidsail.dsapp2sd
