The root of the article is a blog post[1] by a company specialized in
finding and fixing such issues, where they analyzed the issue by
buying and taking apart a Galaxy Note 7.
The article also heavily try to promote the services that this company offers.

The information was then picked by a review magazine that wrote a
journalistic article[2] with that information.

The journalistic article was then picked by slashdot.

It would probably be wiser to ask battery experts before taking any
decision, since:
- That company tried to promote their services.
- They don't point to documentation or information on the margin they
  refer to.
- The battery technology is probably different on the EOMA laptop.
- The casing is probably different too.
- That laptop will probably be used for a time that is way longer than
  the average use time for consumer smartphones.
- The average customers for common smartphones don't mess with them,
  open the device, access the PCB, etc...

What if, for instance:
- You need more space than the 10% figure they mentioned? You probably
  don't want to redesign it twice, and you probably don't want to make
  unsafe laptop either, especially because they will probably be used
  for a very long time by people messing with them.
- You don't need to redesign the laptop because the problem doesn't
  apply it.
