I cannot answer for Fios TV, but for my ethernet only setup, the answer is yes. I have done exactly that. The ONT is located on the south-east corner of the house. I plugged the ethernet cable into an unused jack that went to my wiring closet in the north-west corner of the house. The ActionTec router is in the wiring closet.
There is something like a 300 foot limitation on CAT-5 wiring...
