Not really.
They say that it's theoretically possible in fewer hours because you don't do radio nav and there are one or two very minor differences (like length of QXC) but, in all honesty, you'll take whatever you take and the difference between getting one and the other will be minimal. There are some differences in the cost and simplicity of keeping an NPPL, though (at least for the time being).
I did a PPL in 38 hours in 1986 but I was young and did it all in one summer, so I suppose 35 hours is possible but I think it's unlikely for most people in most circumstances.
