It can and does, but for different reasons.. A banjo gets it's resonance from the skin, not the wood. If you use a real calf, or sheep skin, it will aborb oils, dirt, moisture ext and that will change it's resonance. It can also loosen and tighten depending on humidity, and use. That also changes it's tone. If you use a plastic skin it isn't as influenced by the climates and doesn't absorb contaminates, so it does't change so much.. All this could be a good thing, or bad, depending on cercumstances, and sound you are looking for.
