No.
Where the transfer gears are in the 4x4 4speed is where the 5th gear is in the 5 speed.
So if you did it, you would be making the 5 speed into a 4 speed so it could be a 4x4.
Thats why the 5 speed 4x4 transmission has an extra section in it, to allow for the 5th gear. The vehicles fitted with the 5 speed 4x4 box had the transmission crossmembers in the chassis in a different spot because of the longer transmission.
