Correct, this is a manufacturing error in certain batches of battery, which cause them to catch fire.
Laptops get hot. Any electrics in a confined space like that get hot, but they are designed with heatsinks and fans to manage this.
This isn't a "overheating" problem, this is a technical defect which turns an affected battery into a challenging fire hazard.
The problem is that crew can't be expected to be able to identify every single affected Apple and Dell variant, and identify whether or not they have the rogue batteries.
So, safety first says, anyone with an Apple or Dell should take the battery out for now, either until there's some way of easily spotting an affected machine before it bursts into flames, or until the chances of their being a duff battery are sufficiently remote - either through replacement of affected batteries, or the equipment falling out of use due to natural attrition.
Last time I flew with SQ, they recommended that the battery was removed when running on EmPower anyway, to stop it charging.
On my laptop, if I use the vendor supplied EmPower lead, it's clever enough to know it's running off low-voltage EmPower (like on VS) and not charge the battery. (If I use a generic adapter, e.g. Targus, it will charge.)
If it's the 110V EmPower, like on SQ, NZ, and others, it can't tell, and will charge the battery.
