How to change the name of  "no file chosen"?

kendo.ui.Upload.prototype.options.messages =
    $.extend(true, kendo.ui.Upload.prototype.options.messages, {
     FileChosen: "Nessun elemento caricato."
    });

Hello Federico,

I am afraid that the Upload widget does not expose such message to alter. 

I assume that you need to perform a validation on your page and then display a warning? If that's the case, I would suggest you to refer to the following dojo example, where such implementation is demonstrated with the Upload widget:
