Yes, you are right.
那坐叮叮車可以到太平山纜車嗎?
No. The one takes you to the Peak is "Peak Tram".
Reference.: http://www.thepeak.com.hk/en/5_5_6.asp
You may take eastbound tram and alight at Bank of China Tower (中銀大廈). Walk uphill for around 5 minutes and you'll see it.
OF course, you may take bus rt. 15 @ Admiralty Stn. (金鐘站) up to the peak. That's more economical ($9.8 per single journey only)
