question: When record externally to 10 bit from the GH4, is the footage considered RAW or just a higher bit footage?
It's just higher bit footage. The GH4 doesn't do RAW... for now at least.

Dau, 10bit 4:2:2 from GH4 is RAW.
Our friends at the NFS have a wonderful article describing GH4's capabilities:
where you might pick up that GH4 is capable of shooting external RAW video, but at that moment there were no recorders that could capture that signal. That has changed with the Atomos Shogun release. So now the GH4 + Shogun give us ability to capture RAW footage.
Also, on a separate note RAW means uncompressed signal -- a lossless format such as Lossless Cinema DNG. Again, I believe that Atomos Shogun is the first recorder that can take in such input and thus indeed, the 10bit 4:2:2 signal from GH4 comes in a lossless format making it RAW footage.

Ooooh, that's new to me. Makes the GH4 seem even more tempting.

No, it is not RAW and no where in that article is the word RAW even written. The hdmi external output is 10bit 4:2:2, which definitely gives you better detail and more color information, but it's still not RAW, meaning you will still have your exposure settings baked in.

Currently the GH4 does NOT shoot RAW, though there may be a new firmware coming out when the Atomos Shogun recorder arrives. Lots of speculation about a new firmware with something "special" in the works.
RAW footage is un-debayered sensor data that needs to be processed to produce a viewable image. It's bit depth is the same as the camera's sensor bit-depth and it has the same color space as the sensor, but until this data is processed it is pretty much unusable.
