It is not recommended. I would first tin the terminals using RMA flux to remove the gold. Tin the stranded wire with either RMA or no-clean and soak in IPA, then blow off thoroughly and wash with a good saponifier, bake dry, and then solder the tinned wires to the tinned terminals with the same NC/RMA flux and clean again the same way. Do not use DI water first. Clean off (or at least dilute) as much of the flux as you can with IPA, then clean with water.
Otherwise you will have a reaction between the DI water and the no-clean/RMA flux (white conductive residue).
Any flux residues that might remain after cleaning will be negligible.

Fellow TechNetters:

    Is it permissible to solder a stranded wire to a gold finger pads with either Sn Pb or Pb-free solder?
Typically, gold fingers are electroplated, hard gold.
Any chance of galvanic corrosion?
