Real zeners would, although with -.7 or so volts I would not want to use those cells again... But usually you are talking about several amps charge current, and like Tim posted here some year ago, a transistor with a voltage sensor shorting out / limiting the voltage can be used. If it was a MOSFET with a reverse body diode, yes. Would have to be a logic level type that works far below 4.2 V Vgs on. Bipolar is nice here. No GHz :-)
