Can i move a custom list item from its current default location to a folder within the custom list

[mvcsharepointdev]

I have this code to get a custom list items:-

// Iterate over the retrieved list items
foreach (var listItem in myList.Items.AsRequested())
    {
       try
            {
               // listItem.MOVE](url)

so can i move the list items to a folder named "Completed" inside the same custom list?

Thanks
