If other X86 applications run on the Windows 10 tablet then there should not be any reason that PICAXE Programming Editor 6 will not run on it.
If you can provide details of the tablet, manufacturer, model, or provide a link to the product, we may be able to give better advice. If you actually have the tablet the easiest thing to do would be to install it and see what happens. And it would be great if you could report your results.
