might be pushing it a bit though I have read claims that it works fine. The various charts about what works with what are a little confusing. The manufacturers information has also updated as well via technological advances or plain weight of evidence.
On the old style charts then a 622-19 rim would be good for 28-45mm tyres and ideal around 32-35. This changed, mainly via MTBing, for much wider tyres being permissible so 622-19 rims will often state they go from 28-60mm now. The other thing I've seen mentioned more recently is a trend to wider rims for road use and in this area the rule of thumb I'm picking up is that the tyre shouldn't be narrower than the external rim width. This would actually bear out what my rim stickers actually state, which is different from the official Mavic website until you dig into their supporting documentation.
I use Mavic TN719 rims which will be the same size as yours and are 622-19 with an external width of about 24.5mm. The Mavic blurb states 28-60mm but the rim stickers themselves are 1"-2.4" or 25-60mm. This tallies with the idea that you shouldn't use a tyre that is narrower than the rims external size.
That's a long way of saying I wouldn't personally go less than a 25mm tyre and I reckon a 28mm would be comfier for no loss of speed. You can get 700x28 tyres as light as about 235g which is pretty darn light.
