Instead of using the pane group you could the Docking control and its Panes property - it will give you an IEnumerable<RadPane> and you could find the pane in this enumerable. After that the RadPane has RemoveFromParent method that will remove it wherever it is. Please refer to the following code:
dock.Panes.First(pane => pane.Name == name).RemoveFromParent();
Hope this helps!
All the best,
