Pretty sure the answer is in your owners manual. But we will dive deeper into the answer....The simple answer is yes you can regardless. All your charger is, is a basic power supply. So you can't get more than it can give or "Over Drive" it.
You will find that charging time all the way around is going to be much slower as you are "robbing Peter to pay Paul" this has been a common question for over 5 years with DJI products. They say you shouldn't, but "we" have proven you can with no ill effects (Sans Charging time)...that being said...why bother just get a nice charger for the remote for a few bucks and charge everything as fast as you can. You more than likely have a smart phone charger laying around that will supply more current as a solo charger than daisy chaining your DJI charger anyway.
