The short answer is: No.
The fuel injectors are different, and the electrical plugs for them are different.
There are also some sensors which also have different plugs.
The stock oil metering system is totally different.
Due to this fact, the front oil cover is different, which also makes the water pump housing and water pump different.
Due to that fact, the thermostat housing is different (other than plastic versus cast aluminum) and since your pics don't show the radiator (I assume it's an S4 one WITHOUT the extended neck by the battery), you're going to have a headache of a time trying to get rid of all the air bubbles in the cooling system.
If you are running an N332 ECU, it's possible to take all the original sensors and electrical components and slap them on the S5 engine.
This is a LOT of work.
