In terms of (correlated) color temperature, maybe, but probably not
because the filter would filter out only certain amounts of undesirable
light while allowing certain amounts of desirable light to pass through.
If the light source suddenly has substantial increases in undesirable
wavelengths and a substantial decrease in desirable wavelengths, the
filter doesn't know this, won't compensate for it, and you will still get
more undesirable wavelengths.
In terms of spectral power distribution, definitely not, and it's SPD
that we are more interested in as a light source anyway, less so with the
color temperature.

Unfortunately this is the case.
