Yup, your Leaf's J1772 EVSE will work fine with the Model S. There's just the hassle of moving it between the Leaf and S.
It will probably charge at 30A, although it's possible it was installed at a lower level (the Leaf only pulls 15A). 30A should still generally be over 20 miles or range replaced per hour of charging, so overnight should be fine unless you plan to completely drain the car two days in a row.
For more info on charging a new Model S, see THIS thread.
I don't think you're in an EV Project area, so I'm not sure what EVSE you have. But if it's a Blink, HERE is something to consider.
I started a new thread for this conversation because I was really surprised to learn the info linked about the Blink EVSE inside the Has anyone received a HPWC yet? thread.
I have a Volt right now and am participating in the EV Project. Therefore, I have a Blink EVSE in my garage. I had planned to keep up my participation in the EV Project when Model S arrives. I figure Model S will arrive sometime in summer, and the EV Project (at least for Chicago area) lasts until end of 2013. Now after reading the linked content, I don't like that idea. Hopefully more info about the Blink EVSE and higher amp usage will come out before summer so I'll be able to make the best call. Fortunately my Blink EVSE is of the plug-in variety, so I can just unplug the Blink from the 6-50 plug and get the appropriate adapted for the UMC to take full advantage of Model S's 10kW charging capability.
