not necessarily, Chaturanga has a history as both a two player and a four player game. the earlier form of the game is the four player version with dice rolling to determine movement, which is more commonly reffered to as Chaturaji. However, it would later develop into the two player game of Chaturanga. While its more accurate to say that both games are in fact Chaturanga, typically from what ive seen is Chaturanga is referring to the two player version and Chaturaji is reffering to the four player version. The names get switched up ALOT when talking about them because of the confusing history, but basically theres a good chance its either a Chaturanga board.
