I believe so yes. According to the schematic of the RS422/RS485 HAT - https://www.hwhardsoft.de/app/download/11143497697/RPI_RS485+Schematic+V01-01-00.pdf?t=1505155826 - It only uses GPIO 14,15 and 18.
Waveshare have released this neat little 2.8" 320x240 touchscreen display for the Raspberry Pi!
This device uses the Pi's GPIO output for display, and the Pi's SPI port for touch control.
Installation is easy, you can either use the custom image, or follow the set up guide detailed on the Waveshare Wiki. Please Note. This device does require some simple set up.
