That's if a recent patent grant is anything to go by. The patent, titled "Stylus with inertial sensor," was originally filed back in 2014, but has only been granted by the USPTO today. It details ways in which the iPad Pro's Apple Pencil stylus could be used to work with the trackpad on a Mac via a future version of the company's Magic Trackpad. It's also conceivable that the technology referenced in the patent could allow the upcoming rumored new MacBook Pros to use the stylus on their trackpads. Perhaps even more interesting, the patent details way the Apple Pencil could be used as a joystick:
In response to the mode change commands the stylus may transition between operating modes such as a touch sensor mode and one or more inertial sensor modes. Inertial sensor data may be used to allow the stylus to operate as a joystick, a rotational controller, an air mouse, or other input devices in addition to serving as a touch sensor input device.
