Yes, in the Database window, right click on the object (form/report/etc) and select "Object Dependencies". If it doesn't show up any where, it probably isn't used.
Although that doesn't tell you if it is called in VBA code somewhere. However you can almost totally eliminate that possibility by doing a search for the object name when viewing the VBA and make sure that you have "Current Project" selected instead of "Current Module". It doesn't prevent some evil coder from string concatenating the object name together somewhere; but it's unlikely.
