You probably can, but they would be soft and mushy when thawed. I have allowed whole pumpkins to freeze under the porch for my chickens and brought them in over night to thaw (in a bucket), so I cannot say how they taste. The chickens seemed to enjoy them though! If stored correctly, pumpkins will keep a long time without needing to freeze.
I guess you can, but whole pumpkins take up lots of freezer space. It would make sense to remove the seeds and rind, cube the flesh and pack in freezer bags.
