Yes you can (just avoid using it on any reversed hide panels - just use glycerine soap or a thick conditioner such as Effax or Aussie Leather Care on those).
However, please note that when leather is conditioned with oil, the oil gets drawn deep into leather. This is good for the inside of the leather, but as the oil leaves no residual layer on the outer leather, this part of the hide remains ‘vulnerable’. Therefore, after oiling, it is important to use a product (such as Glycerine soap, Effax Lederbalsam or Sedgewicks Leather Care) that will, in effect, ‘seal’ the leather and will condition and protect the outer layer of it.
