Definitely. Note, however, that this has slightly different semantics. Not worse, just different. The original example would try to set all desired values, whether they were in the form or not. Further, it would do it in a tightly-controlled manner.

Your example will skip values that aren't in the form (probably desirable), and do it in the order that they're passed in from the web client (probably immaterial - but sometimes you care about the order). Further, it will catch parameters that the OP may not care about (again, probably immaterial - if they get filtered out later). For example, the submit button will show up, I think.
