Probably yes, if it could be made in bulk instead of thin films. I'm pretty sure the exceptional property is a large SATURATION FLUX DENSITY, which means it would make good flux-concentrating pole pieces, not permanent magnets.
It took a while to interpret the expression "most magnetic" in the lay article. First hint was where it says "predicted that iron-cobalt should be the most magnetic material." That points to soft magnetic alloys like Permendur / Hiperco, which saturate at about 2.3 teslas.
It's further clarified by the "more information" link, which is an abstract of article titled " Origin of Giant Saturation Magnetization in Fe16N2 thin film". That suggests that as long as the stuff is being magnetized by an external field, it develops an extraordinarily high magnetic moment per unit volume. Might someday be valuable for magnetic disk data-storage technology.

I think it's a sad state of affairs when science press releases are so hyped that even the technically literate struggle to work out what the real 'advance' is supposed to be.

How many mistakes can you see in the penultimate sentence of original news article?
"If the magnets can be manufactured commercially they could allow computer manufacturers to use smaller write heads that could hold more information. "
