Will disconnecting the battery to shut off the check engine light affect anything else?

I currently have a 2008 Impala and as the question suggests I have a check engine light on. In the past if I had this problem I would do the old unhook the battery trick but this is a much newer car than I've ever had and it's like driving a computer with an exhaust pipe. I'm worried about doing something to screw with the digital odometer if I try this, I'm not even sure it would work given how computerized it all is (I half expect there to be some failsafe to keep me from doing it). Any insight into this would be appreciated. Thanks!
