Except it will forever be called that.Not as long as you replace it with a new name. Your "new" problem doesn't sound like a problem of stickiness, it's a problem of never giving it an actual name in the first place, or when it was rolled out.
Look at the Orbis and Durango for names widely used in when the press was rumor-mongering that went away as soon as the devices were revealed. We've even changed our internal code names on projects without much fanfare, as long as the name change represents a milestone in the project or a difference in audience it's easy to cut over.
