I'm thinking the answer is no, because the selective colour would only apply to specific colours in the image and the curves only lightens a certain range of values instead of every level in the image evenly.

This is a common misconception because the rules actually refer to "selection" and it is illegal in the basic ruleset. "Selective color". in particular, can be confusing because of how it is named. For the purposes of DPC basic rules, "selection" means physically selecting certain pixels in an image and working on them separately from the rest.
As long as you stick to the normal blending mode (which is the default layer mode anyway, just don't change it) and use no selection tools, then ALL the "adjustment layers" (layers/new adjustment layer) are legal in basic editing, even if they appear to be working on "selected" portions of an image. Why? Because adjustment layers don't actually contain pixels; they just contain, as it were, data that the layer applies to what's visible underneath it. Since they don't contain pixels, you can't actually make any selections on them.
However, you CAN make selections on the underlying pixel layer and then when you create the adjustment layer it masks off the unselected area and works only on the portion of the image that was selected. This is not legal in basic editing. In fact, it's specifically what the basic rules are designed to stop.
If that makes sense?
