Yes. First you have to map the content control to a customXMLnode. You can easily do that using the Content Control Tools addin from my website:
Content Control Tools
Assume you have mapped a checkbox titled "Check Test" then using this code in the ThisDocument module of the project, you can trigger a msgbox when the CC is checked.
Code:
Private Sub Document_ContentControlBeforeContentUpdate(ByVal ContentControl As ContentControl, Content As String)
Select Case ContentControl.Title
Case "Check Test"
If ContentControl.Checked Then MsgBox "I'm checked"
End Select
End Sub
