I think the England has already rescheduled some exams to avoid ramadan.
If I've understood it all correctly, the exam period is a couple of weeks. The education board is free to re-arrange in what order exams are scheduled and the days any way they want. Ramadan is only 11 days. So there's days in the exam period that isn't concurrent with Ramadan. What they did was that they put the most popular exams during those days. But there's still plenty of exams that is on Ramadan.
IMHO not doing this would be to go out of their way to be dicks. Re-arranging it for the Muslim's benefit is zero cost. So why not? I really can't see a problem here. Sounds like BNP hysteria to me.
