Can you smoke marijuana on Suboxone?

Unless they specifically tell you not to...yes. I'm sure they would encourage you not to, or at the very least, to smoke as little as possible. But I don't see why they would specifically tell you not to. If you are in a Suboxone treatment program, then clearly the most important thing for you to focus on right now is abstinence from opiates. When you have mastered that, you can move on to quitting pot. I am in a Suboxone treatment program, and they have never forbidden me to smoke pot. They just encourage me not to.
