It's not clear at what frequency, exactly, the ESR should be measured at. Perhaps near the cutoff frequency (i.e., Xc ~= R, i.e., around the resonance valley in the ceramic cap's Z(F) curve).
It's at least borderline, and probably too low at the worst. For sure, it's a decade away from the ideal value (~0.1 ohm is in the middle of the stable region), so whatever you do, you'll be a damn sight safer with that kind of ESR added in.
Play it safe and add the resistor.
There's an off chance you can find an aluminum polymer that size with high enough ESR, or a tantalum low enough. If you don't mind these types, of course (more expensive, and "house parts" may not fit the spec, or exist).
