Yes because Earth is not a closed system. If you reduce the speed of rotation and radiate the acquired Energy into space the total angular momentum (in the universe) stays the same but the angular momentum of only Earth + atmosphere changes.

The transport of angular momentum from the Earth by radiation is very small, and the change in that due to changes in wind is even smaller.
