No. You must use begin rescue end to catch WIN32OLERuntimeError exception.
If you want to let the script continue, write the script like following. 

  is_ok = true
  begin
    obj.ActiveSelection
  rescue WIN32OLERuntimeError
    is_ok = false
  end
  if (is_ok)
    ... 
    continue script non exception occurred. 
  else
    ... 
    continue script when WIN32OLERuntimeError occurred.
  end
