razor view with anonymous type model class. It is possible?

The short answer is that using anonymous types is not supported, however, there is a workaround, you can use an ExpandoObject

Set your model to
@model IEnumerable<dynamic>

Then in the controller

from p in db.Articles.Where(p => p.user_id == 2)
select new
{
    p.article_id, 
    p.title, 
    p.date, 
    p.category,
    /* Additional parameters which arent in Article model */
}.ToExpando();

...
public static class Extensions
{
    public static ExpandoObject ToExpando(this object anonymousObject)
    {
        IDictionary<string, object> anonymousDictionary = HtmlHelper.AnonymousObjectToHtmlAttributes(anonymousObject);
        IDictionary<string, object> expando = new ExpandoObject();
        foreach (var item in anonymousDictionary)
            expando.Add(item);
        return (ExpandoObject)expando;
    }
}
