Remove Menu Button from Title Bar in KitKat
Short answer is no, there is no way to remove the "Menu" overflow button from within apps in 4.4, even on phones with a hardware Menu button.  This was an intentional change by Google in KitKat to unify the interface across devices.

It's possible to remove this overflow button with some OS modifications, and many custom ROMs do offer a toggle for this.  However, it requires rooting the device, unlocking its bootloader, and installing a 3rd-party modified OS.
