Tire compatibility?

I have a set of Weinmann CN520's that came stock on my bike and I was wondering what would be the skinniest set of tires I could fit on my rims? I currently run 28's, but i wouldn't mind going slimmer.
I am aware of various fit charts out there and it says the recommended minimum size is around what I have now but I want to know how far beyond the recommended I could safely go.

I don't see much regarding using narrower tires on a wider rim. Is anyone out there running tires that are skinnier than recommended for their wheels?

I couldn't find any specs on your wheels when I googled them but if you know the inner width of your rim, you can sufficiently tell what tire size is appropriate.
My rims have a 16.3mm inside width and some charts say no skinnier than 25c while others say no skinnier than 23c.
My bike came with 28c and I put on 23c. No problems yet after about 150 miles.

What the charts give are just recommendations so depending on your riding style you should choose your tire.
I ride my fixie as if it were a road bike. (as in i rarely jump down curbs and generally pamper it) This riding style allows me to run skinny tires without fear of pinch flats.
If you bunny hop your bike or are generally rough with it, you should keep well within the recommended limits or risk pinch flats.

Anyways, long explanation but I hope that answers your question.
