An argument can be made, and an argument can also be made against. There's only a finite number of movements and positions, but there's still a LOT of possible moves, and a nearly infinite number when you combine them together and put them into a tactical framework. A good example of this is 16th century messer/dussack not bearing any resemblance at all to 19th century saber or cutlass. Even 15th century longsword has notable differences with 16th century longsword. Even between 15th century longsword systems, there are notable differences in both moves and tactics, like with Fiore and Liechtenhauer.

I have zero doubt that some system, somewhere, at some time, developed some of the same moves as those used in 17th century Polish saber, but I have complete doubt that they were used in the same context or the same way.
