well if you mean just changing the title of the team from "International All-Stars" to something else yeah.
just edit the "teams.dbf"
get
DB Commander or another DBF editor.
then scroll down untill you see the line for the Internationall All-Stars, and change the TEAMNAME ("All-Stars")section which is the teams name, and the CITYNAME ("International") section which is obviously the team Citys name
