No. Here's a Wikipedia page about incorporated towns (similar, incorporation as a term regarding a governmental jurisdiction.)
https://en.wikipedia.org/wiki/Incorporated_town
The term corporation here refers to a grant or charter from the higher level of government authorizing the lower level's legal authority.
In contrast, corporations in the business sense relate to official government recognition of the corporation as a legal entity (similar to a person, in that it can own property, enter into contracts, etc.)
