Hi,

I want to use the NFC on my phone to turn on a battery-powered device (which would have an embedded NFC tag). Is it possible to replace the 'on' button with a NFC actuator or would it have to be in sleep mode to use the excitation of the NFC tag as an input?

Yes.
Some experimentation might be required but most likely you only need to detect energy at 13.56 MHz and condition that signal to control your battery-powered device.
