Certainly! The limit is your creativity. My first idea: generate very large scale 2D noise. Choose a threshold to divide it into regions. For each region, choose a direction of motion. Design a “mountain envelope” function that considers distance from the nearest border to create mountains/subversion zones based on the direction of each plate and the shape of the border.

You can also do similarly for water erosion, plotting channels where it runs downhill, carving a little on each cycle (and some terrain engines do).
