1) The admech warlord traits have a specific exemption for cawl but do not limit other named characters from taking one.
2) There is an exemption for named characters taking an arcana mechanicum but an adeptus mechanicus warlord can generate one for another model
Larson has adeptus mechanicus and mars as keywords but not faction keywords.
You need to give more information, especially the book it's found in. A quick Google says it's from Kill Team: Rogue Trader.
IIRC you can't use Kill Team exclusive datasheets in regular
40k, so it's a moot point. If I am wrong on that and there is a rules citation that can prove otherwise, please let me know, I don't really keep up with Kill Team material.
