Two comments:
1. According to multiple sources, A330-200 and A330-300 have the same fuel capacity. So where does the -300 put the fuel that the -200 puts in the centerwing tank if -300 has no centerwing tank?
2. Consider that A330-200 and A330-300 also have the same Max Take Off Weight (MTOW). A longer fuselage means more empty weight, so less payload if MTOW is held constant. Adding a center tank on a -300 fuselage would then make no sense because the extra empty weight means you can't fill that center tank. By comparison, each time Boeing stretched the 767, it also increased the MTOW, thus increasing payload weight capacity to match the increase in payload volume.
