Are the driving motor cars of modern DC EMUs such as Networkers,
Junipers, Electrostars and Desiros independent multiple units in this
way? It seems that no set is ever run without a pantograph trailer car
- is this because the motor cars rely on the electronics or other
systems in this car, even when running from the DC 3rd rail? Or can
the motor cars run seperately from the rest of the set?

AFAIK all the gubbins and even the motors are in the car that has the
pantograph whereas the cars at the front and the rear which although they
have no motors have the shoegear.

For DC Electrostar, you are comprehensively wrong.

To explain a little mo, they are capable of being marshaled in
3, 4 or 5 car units. There is a simple reason why there is
always a PTOSL, as this is where the main power and control
cables routes cross over from one side to the other along the
length of the vehicle. If it was omitted, the inter-car jumpers
would not match. It also, on versions with retractable shoegear,
controls their air supply.

There is one motored bogie on each driving vehicle (DMOS), and
one on the MOS, There are none on the PTOSL
