WSJ makes it sound like a certainty, but the article gives no details
whatsoever beyond "someone suggested that ... perhaps ...".

It doesn't really make sense. As far as we know, 9M-MRO did not send
any ACARS messages after the transponder went silent. But even if it
did, Malaysia Airlines did not have the SATCOM option for ACARS, so
downlink must have been to a ground station. Ground-based comms are
range-limited, so Rolls-Royce would presumably know, or the ACARS
operator could find out, which station received the messages, and that
wouldrestrict the search area, and not widen it to a huge 2000+
NM-radius circle.
