Making orbit is a single hard step; raising orbit, which is all that making it to the moon requires, can be done more gradually (with low-thrust/high-efficiency engines, on-orbit resupply, etc). So if you can get off the planet you can get anywhere... but that doesn't mean cost-effectively. If your planet is such that it takes a Saturn V to launch a cubesat, it may simply cost too much to make it to the Moon.
