Yes, you can run Windows XP on an Android Tablet or even on a phone. Look at the video. Though, it would not be very convenience thing to do so. Your device will become horribly slow because XP is not at all a CPU efficient OS. This type of hardware is built for Android and not for any old Windows operating system. But you can do it if you like to do so. Just go to the source of the video (YouTube) and read about the process.
