When departing Runway 24 at TEB; we were cleared for the RUUDY 4 Departure. The Departure was a mandatory altitude of 1;500 FT MSL at WENTZ. Before reaching WENTZ; there is an unnamed dogleg intersection. When passing the dogleg; the aircraft began a programmed turn. We confused the dogleg intersection for WENTZ and began a climb to 2;000 FT MSL (which is the altitude at TASCA). We were still about a mile and a half from WENTZ. The flying pilot realized the error at the same time ATC noticed that the climb began early. ATC then cleared us to 6;000 FT. Better monitoring of the FMS and multifunction display would help prevent a problem like this one. Also; 'naming' the dogleg intersection would help prevent confusion.
A CE560XL departed on the TEB RUUDY 4. At the dogleg turn before WENTZ; the crew mentally connected the turn and climb so continued toward 2;000 FT early. ATC then cleared the flight to 6;000 FT.
