Sounds like total BS to me. Number one, he would have to take apart the whole head on the car to see the chain which is no small job and requires a new valve cover gasket. There is a chain tensioner as you said and yes it that can wear out and there is also a little push pin thingy on there that can fall out of place that can cause issues. But this guy is total bullshit. Those chains are meant to last a lifetime and don't wear down like a belt!
Acutally, you don't need to pull the head to see the chain. If you remove the valve cover, the chain is visible. They can crack and wear, although it takes significantly longer than with a belt. Depending on the vehicle, they will need to remove the front cover of the engine, which may or may not involve taking the oil pan off. Then, new front crank seal, new chain, new tensioner, and reinstall of the chain. The last time I did one, it took me 7 hours to do. So, at $60 / hour for labor, the price may seem a little high, but it's close to accurate.
Hope this helps!
