ARMs vary from simple microcontrollers to the SoCs used in smartphones and tablets.

The former, probably not.

The latter probably have something similar --- and they're even less publicly documented than Intel ME/AMT or AMD's equivalent.

An ARM CPU is just a core. SoCs probably do have this, pretty often. I know the Raspberry Pi's got a separate processor core running closed-source Broadcom software, and which has access to the system's memory.
