The shaft lengths are different between the two clubs so it would materially impact the length (speed) and driver swingweight unless you changed out the weights as well.  You can try, but you might not get the results you are anticipating.

if you want to switch shafts, you can try out different shafts that are the correct length from any Titleist fitter and order the shaft you want separately.

Go for it!! The worst that will happen is you will hit more fairways! I play my 910f 4 wood at 43" which is only 2" less than my driver at 45". It wasn't that long ago that we played 43" drivers with steel shafts!!!! 

Go for it!!!
