You won't find these capacitors in the schematic for the laptop / its motherboard because they are part of the CPU package. These capacitors are there to provide filtering for the power going into the CPU die, and generally that power needs to be very "clean". However, I'm not fully convinced you knocked them off unless you were really rough cleaning the old paste. Like Bill mentioned, they could be unpopulated from the factory.
There's relatively low risk to testing out the laptop in its current state, it may not want to boot up, but you won't do any long term damage to the machine / its CPU if those capacitors are actually necessary.
Also, this may not be the same exact CPU, but note that some capacitors are missing in this similar AMD SoC:
