You can't get rid of the "co". It's needed for disambiguation.

For example, here in Texas, the City of Dallas is located in Dallas County, but they are separate things. If you want to pay a parking ticket that you got in the City of Dallas, you need to go to the city's web site. If you want to pay your property taxes, you need to go to the county's web site.

Also, the City of Austin is located in Travis County. There is an Austin County, but it's 100 miles (160 km) away. The only connection is that they are both named for Stephen F. Austin.

Interesting. Here in CA we have a few fused “City and County of X” governments. In those cases, the borders are one and the same, and there is only one governmental entity in charge of it. Mostly, this is convenient.
