Yes, losing muscle mass while in a caloric deficit is a common occurrence. If the body is not receiving enough calories to meet its energy needs, it will start to break down muscle tissue for energy. This process can be mitigated by ensuring adequate protein intake and engaging in resistance training, but some muscle loss is likely if a significant caloric deficit is maintained.
