Yeah, the TOS states that indeed... I asked the same question to the NFSW support, hoping for a reply soon.
(not counting on it though)
Edit:
Just got a reply from EA support:
Thank you for contacting Electronic Arts.
I appreciate your interest in Need For Speed. I assure you my continual support in getting your issue resolved.
Having reviewed your email, I feel that you want to know that it is legal to change the country region. I would like to tell you that it is illegal to change the region, as it comes under providing fraud information. These discount coupons or some promotions are designed by developers, so please wait you will also get some for your region.
In case you have any doubts, please feel free to get back to us with your email address.
