No, a majority of miners cannot decide to change some aspect of the protocol. If they do, they will be mining on their own fork. Not only would the majority of miners have to agree, but so would all the users and businesses have to agree to use that fork.

I was under the impression that whatever rules the majority of miners agreed to run on would control the network, hence the concern over a 51% attack. Therefore, if the majority of miners decided to change some aspect of the bitcoin protocol, they could do so, for better or worse.

There's a HUGE debate raging in the noobs section over whether things like the max number of coins can ever be changed.

Is this possible? Or is the 21 million coin limit a stone set rule?
