If the FA/GA gave you any pushback for doing so remind them that they would be in violation of Federal law by accepting a bag with such a battery (and no removing the battery cell from a laptop doesn't remove the risk since most laptops have an embedded battery for CMOS).

This is not correct. The FAA
recommends that devices containing lithium batteries, such as laptops, not be checked. However, only loose, un-installed spare batteries or damaged batteries are prohibited in checked baggage. IATA has more complicated advice/rules depending on size, etc. (which, for example, excludes small CMOS batteries).

In short, it's not illegal to check a laptop. It's just a bad idea.
