yes, that's exactly how ideal zeners work. real zeners, tho, have curves. if you put too little current through them, they wont zener properly, and as you increase the current, the voltage increases slightly, maybe 5-10% before it starts to get too hot. also, the breakdown voltage varies with temperature.

if you need very accurate reference, then you buy a voltage reference, not a zener.
