of course yes - tone equalizer and filmic are two different tools like spoon and fork. you can eat your soup using a fork, but thats will be not a convincing solution - as well as treating a steak with a spoon. I fact it makes sense to use both for a meal 
tone equalizer’s scope is correcting tonal values without being limited to a tonal range. So you can push highlights without bothering about clipping.
Filmic is used to bring high dynamic range of the captured scene into low dynamic range for the target media → it takes care to avoid clipping by tonemapping.
