Well, as I stated, if you bypass the existing electronics you have a DC can-motor loco, so using DC would be fine.
But, if your question was "can I run it on DC as it sits?" (maybe I misunderstood) - the answer is definitely no, as the electronics expect AC input, and would probably be damaged if you put DC through them. I think that some loco boxes/instructions mention this.
I believe that some of the newer Lionel/MTH/etc locos can handle either A/C or D/C as input current (they sense it and handle it appropriately), but don't quote me. I don't buy much new product (I'm full!).
