Yes you can, its never referenced in the movie what it is. It could be a depiction of any battle between Ruins empire and the jedi. Fans of the Pre-PT EU need to understand pretty much all the events in the books never happen according to the movie continuity.
Any sort of quote from the movies sure as hell doesnt reference anything to the EU.
The novel only showed Darth Maul thought the Sith came around 2000 years, it's not their entire history.
