Yes, you can safely remove the battery to store the vehicle.
In the nineties some manufacturers started the idea that when removing the battery, the PCM would lose its programmed state and you would need to reprogram it to start the vehicle. I have no idea of the actual reason for the system, maybe to ensure vehicle owners gets back to the dealers or a theft prevention.
That was a failure and since then manufacturers has reverted to the normal procedure whereby no reprogramming is required but most engine control units are inteligient units and some relearning would be required whereby the vehicle has to be driven over some distance before it gets back to its optimum state.
So don't be surprised if the vehicle does not perform according to what it was before removal of the battery. Some driving later should get it back.
