In every reaction, energy is either always released or absorbed. No, change in a matter cannot take place in which energy is neither released nor absorbed. That is as far as the extent of my knowledge on the subject.

Energy is always released or absorbed in a chemical change.

I suppose it is theoretically possble to have a neutral energy reaction, but I am not aware of one example.
