Short answer, no.
 
Long answer:
The miniwave uses a DAC0800LCN.  Full scale error is +-1 Least
Significant Bit and nonlinearity is 0.19%.  Just looking at the
nonlinearity, 0.19% of 10 volts, or the full scale Miniwave output, is
19 millivolts.  1 volt = 1 octave, 1 semitone = 1/12 = 83 millivolts,
and 1 cent = 83mV/100 = .83 mV.  19mV/.83mV = 22.9 cents.  So that's the
accuracy you can expect from the Miniwave.  You may get better results,
but that's not guaranteed.
 
Pitch discrimination varies on the context.  For monophonic lines you
may only be able to discern 3-8 cents of pitch resolution.  For chords,
where you can hear the beating of the harmonies, pitch discrimination
can be better than 1 cent, particularly if you're using a just tuning.
For equal temperament, 1-2 cent accuracy is adequate.
 
As a comparison, the MOTM-300 VCO published specs correlate to a pitch
accuracy of better than 1.4 cents from 50 Hz to 1600 Hz, and better than
4.4 cents from 25 Hz to 6400 Hz.

Subject: [motm] Quantizing
 
Another thing I worry about (thought I don't have a miniwave) is the 
relative low resolution of the 8-bit setup in the miniwave... is 255 
levels enough to quanitize accurately, in a chromatic way?  Or is it 
just better for octave-octave-octave stuff?  Just curious what your 
experiences are, and, of course, if there are any "official" plans 
for a quantizer.  I agree that using a MV just for quantizing is 
probably a waste.
