imho there's too many variables here, but the one that's been neglected is fluid speed. my assumptions from the above comments lead me to believe that:

A) you pull approximately the same overall volume of smoke through either large or small hoses
B) it takes you about the same time period to achieve 1 full pull

therefore, the fluid flowing through the smaller diameter hose must be flowing faster. not fast enough to even bother with speculation of laminar vs. turbulent flow affecting flavor, but certainly faster. added on top of that, if you're using a disposable tip, you can think of that like a nozzle, increasing velocity at exit.

maybe there's something there, maybe not...

anyway, what we obviously need is someone with way too much time on their hands to tap a hookah base for a pressure transducer, construct a hose with interchangeable diameter tubing and a pitot-static tube near the mouth piece and let the science-y fun begin
Haha I was reading through the first page of this and this was the first thing that came to mind that was missing.

I think the reason for the perception of more taste comes from the initial stream of smoke coming out of the hose tip is more concentrated due to the gauge of the tip.
