I'd say certainty in such a belief would be dogmatic. But I don't think it's at all dogmatic (or wrong) to say that in the distant future it could maybe become possible.
If one merely says "I believe there's a chance we may one day be able to upload our minds to a machine", I don't think that's dogma. Even if one says "I believe there's a chance we may one day be able to upload our minds to a machine and retain continuous consciousness in the process" (as opposed to basically just creating a mental copy of oneself), I'd say that also isn't dogma, even if the odds are lower.
I would actually say "our current scientific understanding of the brain precludes it" is dogmatic. Unless you mean "we don't yet know how we could go about it given our current limited understanding", then sure; but asserting that something (especially something that doesn't violate any laws of physics) will never be possible is a positive, definitive statement, and one I also don't think is true.
We just know it would be enormously difficult and complex and that it's extremely unlikely it would be possible within the next few centuries, and may never be possible. There's nothing we know about right now that would fundamentally make it impossible. It's all just matter and information.
The definition of dogma, according to Google, is "a principle or set of principles laid down by an authority as incontrovertibly true". Claims of incontrovertible truth are dangerous, whichever direction they're in. If some transhumanist wholeheartedly expects they're going to be inside of a computer by the time they're 80, then that would be dogmatic, but I've personally not seen anyone with such an attitude.
