I mean... I can at least tell you that we do this in practice all the
time (with generally no issues). The SPI flash is not electrically
isolated, so yes, you're gonna leak some current into the SoC when you
do this (there are 100Ohm limiting series resistors so it's not a
complete short). I've never heard of a Chromebook board dying from
this but I can't legally guarantee you anything, of course.
