No, as this would lead to parsing issues. We need to be very specific _where_ the `light-dark()` with colors and the `light-dark()` with images is used. See https://github.com/w3c/csswg-drafts/issues/12513#issuecomment-4085662455 for the proposed syntax details.

Practical example being `background: red light-dark(blue, url(dark.png));`. With a dark color-scheme that would be OK, but in a `light` color-scheme you’d end up with `background: red blue` which is invalid.
