You could try this:
I've referred to the checkboxes by name as they appear to be numbered sequentially and you only want changed the linked cell for some of them.
The row of the linked cell is determined by the position of the checkbox.
Sub LinkCheckBoxes()
Dim chk As OLEObject
Dim iLinkOffsetCol As Integer
Dim iChk As Integer
iLinkOffsetCol = 3 'number of columns to the right for link. 3 = col Z
For iChk = 107 To 210 'most recent checkboxes
Set chk = ActiveSheet.OLEObjects("Checkbox" & iChk)
With chk
.LinkedCell = .TopLeftCell.Offset(0, iLinkOffsetCol).Address 'reassign the link
.Object.Value = False 'untick the box
End With
Next
End Sub
