In North America, maximum load for a circuit is 80% of breaker rating so for standard 15A/110 outlet, that means a maximum 12A charger.
EU design may be limited by the UK, some of which utilises "ring circuit" wiring which permit a maximum appliance load of 2/3 (67%) of rated maximum, i.e. 10A.
The limitation isn' t the car, but general wiring standards.

You could open the charger and at least see if they still use a power supply that can handle 240V too.
Rereading the threads the boards have another colour and another sticker regarding the firmware. It seems in the NA version the charger will allow up to 12A while in the EU version it is limited to 10A. More V and more A means more power means more heat. So while I don't mind using my 240V charger at 120V I don't know if I would try the other way around unless I can keep an eye on it and measure the heat once in a while. Although it would probably work fine, it is not fun if it turns out you would slowly melt your charger and it stops working after you used it for a while.
