So many explanations, but none cites simple technical point. As some mentioned, yes lower rated charger supplying higher load runs risk of burn out. Now, if apple makes "super quality" chargers which are capable of supplying to higher loads (although it would be surprising if thats true, as it increases manufacturing cost for usually unrealised "quality") thats a different story. If my charger is rated 60W I would NOT use it on a machine rated 85W. If someone did and didn't blow up the charger then s/he must be lucky, but its only matter of time before its toast. With that said, if the circuitry employs current limiters then you wont blow up the charger by using it on higher load, but it might well be incapable to charge battery at the rate its draining.

@Gabe, so it falls inline with expectations. It would charge slower. How long have you been using 60W on MBP? Did you ever try using your mac with battery charging from less than 25% while watching flash video with full screen brightness? (the idea is to draw max power).
 
If you did, and the charger is safe that confirms presence of current limiters which ensures safety. Thanks for sharing your experience.
