Hi HTC, yes I have frozen it as well without an issue. Just defrost and use. I normally empty the unused portion from the can and then freeze it in an airtight resealable container or ziploc.
I'm sure you've already found this out, but you need to buy coconut milk for curries, not coconut cream. The latter is for pina coladas and deserts. I, too, have frozen both with no problems.
