There's nothing which specifies a pickup for neck or bridge position. Those indications are only recommendations. Many replacement pickups aren't specified.

Theoretically, the difference between the neck and bridge is that the neck pickup sounds a bit BRIGHTER. You'd think it's the other way round, but it has to be brighter to compensate for the less twangy sound as you move away from the bridge.

Thus, depending on the bridge pickup of choice, if it's a relatively low output one, it might sound a bit darker in the neck position than it would in the bridge.

That said, a bunch of people put Duncan JB's in the neck and bridge positions of thier guitars.

You can put a weak or a powerful one in there. The whole neck or bridge voice is really for calibrated sets. If you are using pickups that are not part of the same calibrated set then it's recommended position loses it's relevance. There are some exception but they are few and far between.

What pickup are you thinking of puting in the neck of what guitar?

The primary difference between bridge and neck pickups is which "end" of the pickup the leads (wiring) come out of... In order to "properly orient" a bridge pickup in the neck position the leads will come out on the "top" rather than "bottom" of the pickup and thus have a greater distance to go to reach the rest of the electronics. It's not really a problem though, just a fact...

^pole spacing is the same on the bridge and neck pickups for nearly all pickups which means it's not really an issue.
