it is said that full frame aperture equivalent of 2.8 to aps-c is 4.2. does it mean that shutter speed of aps-c is one stop slower that full frame on the same aperture? given the same focal length equivalent e.g. aps-c 23mm and ff 35mm.

You’ll get 1/80s with the same blur since you have the same field of view. Depth of field will be different though, the FF will be shallower.
If you stop down the FF to f2, then you’ll get similar depth of field, but then you’ll have to raise ISO to compensate.
