It's established in AUDIO: False Gods that a TARDIS can be destroyed by flying it into the heart of a sun. The Stolen Earth also said that the Daleks had found a way to destroy TARDISes, and that the Doctor's TARDIS was almost certainly going to be destroyed by that process. So yes, there are ways, established in narratives, that a TARDIS can be destroyed by someone other than a Time Lord. To speculate only mildly, there's really not much of a Time War unless someone other than Time Lords, specifically the Daleks, can destroy TARDISes.
