He says in one of the comments that he was able to get a signal you could hear from around 20 feet away.
I suspect that’s unlikely from my own experiences on this stuff. Perhaps 20-40cm is more likely.

#12Wow. I wonder how far from the phone this signal could be detected.

#14Why does it say it's an FCC problem? What are the consequences that Apple may face?

If you are disregarding that detail of the story, why not dismiss the author outright?
Re: iPhone audio detectable with AM radio
#17This is not surprising. We’ve been using AM and FM radios to debug circuits for decades. They can pick up oscillations and instabilities. But the range is centimetres at best. So much so the antenna gets used as a fairly directional probe.
In a later tweet he says the signal is pretty strong and that he could detect it from 6 feet away
Really why is this a surprise when you can hear the phone blips and buzzes from the RF induced pickup on shitty hifi equipment.

Why would you assume that his experiences and yours are the same?

Just a few meters, as per the article. I'm guessing if you can't hear it on the iPhone's speaker, it won't be audible on AM radio either.
But I very much doubt at the stated range. The EMC guys would be all over that.
