Anyway for a charged Telsa to charge another Tesla?

Yes.

Tow it.

Tesla Model S can be recharged by towing it with a Model X, but it’s not recommended

It'd be dangerous to simply connect the two packs together - the potential difference could lead to massive current flows that could damage the batteries.

In principle someone could build a box with a plug in each end and a DC DC converter in the middle to allow direct DC charging from one car to another safely (using Supercharger communication protocols) but I haven't read of anyone developing or even seriously considering such a thing. The use cases would seem to be pretty rare.

It would be technically possible but it's not as simple as connecting both batteries. There are charging stations that accept 400 Volt DC input which would in theory work when fed by a Tesla battery, but I would highly recommend staying away from messing with 400 Volt DV.

Probably not what you were asking but the S is charging when getting pulled by the X.

just curious ... if i had to help a stranded fellow Telsa owner.

Awww noone posted the towing the model s with the farm truck video and now i cant find it.

So in theory you could connect two Teslas today, using that box and a pair of CHAdeMO adapters...

It's possible, but Tesla has done their best to make sure that once electricity goes in to a Tesla, it only comes out through the normal vehicle systems. So getting the electricity back out requires a fair amount of hardware hacking.
The easiest way for one Tesla to rescue another one is to bring a generator trailer (anything less than 2kW is probably completely futile, and really you'd want 5+)

Or a trailer with a couple of Powerwalls?
