I'm not sure I understand your question. The center of mass is a mathematical point that is useful for describing some physical properties of a body; it's not a physical part of the body. You can't "remove" the center of mass. (Of course, if you remove any portion of the body, you may affect the location of the center of mass of the remaining material.) Often, the center of mass is not even within the material of the body: For example, the center of mass of a hoop (a donut, say) is in empty space.
