I allow it IF the EK spent the money/time/whatever to make their weapon a spellcasting focus. The Ruby of the War Mage is the quickest way, but weapons that cost +100 gp and also count as foci are available wherever fine weapons are sold.
It's a small change, and doesn't really affect much, but it creates an in-universe solution, which help make it look right. It also means that being disarmed is a slightly bigger issue, since it would interfere with spellcasting as well.
