Here is a small example how to do this in a table. First get the Content Control, Exctend the selection to the previous line in the table cell and delete the selection.
Sub test()
Dim rng As Range
'Get your Content Control here based on your variable reference
Set rng = ActiveDocument.ContentControls(1).Range
rng.Select
'Move outside the Content Control
Selection.MoveRight wdCharacter
Selection.MoveRight wdCharacter
'Select Line Up
Selection.MoveUp Unit:=wdParagraph, Count:=1, Extend:=wdExtend
'Include the paragraph from previous line
Selection.MoveLeft Unit:=wdWord, Count:=1, Extend:=wdExtend
'And ... Delete the selected area
Selection.Delete
End Sub
Hope it helps
