Match.com own "Match", Can I still use "Match" in a company name such as "FireMatch" (this is just example name)

You question can never be answered as a hypothetical. If you are making fire extinguishers, probably. If you have an online dating service, prepare for a cease and desist letter followed by a lawsuit. You need to consult a local IP attorney or business attorney that does a lot of trademark work. You will need the attorney on a continuing basis if you are serious about starting a business. Final comment, originality in picking a business name is a win-win: all good will your business develops will clearly belong to your company, and you will avoid the ruinous costs of trademark infringement litigation.
