Nope.... not true. When the brain is working efficiently, LESS cortex is involved, not more. Some examples... dyslexic readers use MORE cortex (and more bilaterally) than fluent readers when performing reading tasks (fMRI studies). Patients with multiple sclerosis use MORE brain regions to perform the same cognitive tasks than do healthy controls performing the same tasks. Same for those with traumatic brain injuries.
The empirical literature is full of examples like this. When it comes to cognitive efficiency, Less is More. (this is what I do for a living, by the way).
Again, the 10% thing is merely a metaphor... kinda' like, if I didn't spend 90% of my time surfing TDPRI, I'd probably get a lot more done.
