Yes, as long as the device shows up as an evdev device. It can come directly from a kernel driver, or a user space driver that creates a new evdev device using uinput. As an example, http://who-t.blogspot.fi/2012/07/elographics-touchscreen-setup.html talks about setting an Elographics touchscreen for X, but while doing it they create an evdev device that also Weston could use. I haven't tried that, but I can't think of any reason why it wouldn't work. The touchscreen of Samsung Galaxy Nexus works. Mind you, that we have no pointer emulation from a touch device. An input device can never be both a pointer and a touch device, and we haven't implemented any pointer emulation. Given that touch device support is practically non-existant in the Weston demo clients, apart from one special demo, you can't do much without writing your own application or improving the demos. However, the protocol and server bits are there and ready for use. Oh and note that we talking about Weston. Wayland says nothing about how you get input to the server. Weston's DRM backend uses evdev devices.
