I mean, yes to both. Depending on local political boundary systems, it might be part of the main city or not.
Reasonable commute has a different definition for different people. Some people don't commute for work, so two hours to city center is fine if they only go a few times a year. Some only commute for work a couple times a week and an hour and a half sucks, but is doable if the housing is better enough on whatever dimension. Some will be able to move their job to the new location.
If the new town has appropriate zoning and desires, a handful of companies in the city center may setup offices there to reduce office costs and attract workers that are in the periphery, instead of making everyone go into the city center.
This definitely happens around Toronto, just from looking at the density of roads on Google Maps. There's plenty of pockets of density in lines out from Toronto, and there's also several named places where there's no clear boundary between the names (there probably is at other levels of detail).
