If that is the only question the answer is yes, just check to see if your name is available to register or buy. However, there are pros and cons to doing so. You may choose to do this mainly when You are the Brand. Industries, where this may be the case, include personal coaching for health or coaching of any kind. The main downside to this is let’s say you get stupid tired of what you are doing but have created a crazy successful business. Your name as the business title will make it much more difficult to sell.
PS register your name as a .com if you can whether you mean to develop it or not. You don’t want your crazy ex to get a hold of it.
