Track front wheels normally (but not always) have a high flange hub, to match the rear hub. They also have a traditional bolt-on axle. Road wheels generally have a lower flange hub and quick release. Some road wheels are also built much lighter (but there are exceptions, of course). However, basically a front wheel is a front wheel. A road or track wheel will work the same.

Retem is correct, however....they are usually cheaper per wheel when bought in pairs.
