For positioning what?
Assuming that you meant the rider then I'd have to say yeah, The shorter headtube would hold the bars 1.5cm lower but the lower BB would also require the rider to sit 1.5cm lower. But that's a big variation on the BB height unless you're comparing a road to a cyclocross frame.
