Yes and No

If you are of the opinion that choke is measured in constriction then it really doesn't matter what the bore dia. is. The shot column will fill out to whatever bore dia you have. So the constriction will still work.
But in my opinion the actual choke constriction means nothing.
What matters is how the gun puts a certain load on the pattering board. Example Gun A might pattern a given load at 70% at 40yds but only have .020 of constriction but gun B but may have to have .045 of constriction to do the same thing.
So constriction is only a starting point, actual patterning is the only answer.
