I have observed that a lot of art quilters refer to it as the studio but that is just my observation and by no means a tested theory. I actually love the term studio but have never gotten into the habit of using it. In my house my sewing room is where I piece. It is also my guest bedroom so everything is put away when guests come to stay (usually by brother so we often call it Dan's room). My longarm is in a back bedroom and is referred to as the longarm room. Both are upstairs in my house. The guest room is in the front and the longarm is in the back. So when I announce to my DH I am going upstairs to sew, he usually asks front or back, or he asks regular or longarm? LOL
