That is good enough to convince me. Their frequency ranges overlap and the MRI is always emitting pulses with variable frequency. Although there wouldn't be much energy available at the range of tens or hundreds of meters, the sharp pulses could create high peak voltages, cause a breakdown and fry something small. It still could be a made-up story, but it's plausible, at least for devices reasonably close to the machine.
