This construct mount acts in most ways as a druid animal companion, using the character’s alchemist level as his effective druid level.
And then they describe the ways it is different. None of those differences should prevent the archetype from being applied. But I’m not seeing much synergy there either and a lot of the benefits contradict and probably wouldn’t work.

My understanding was that the phrase "acts in most ways as a druid animal companion" meant that they were similar, but do not "count as" the Animal Companion class feature, and therefore do not qualify for most feats/abilities/archetypes that specifically affect Animal Companions.
Class features that behave as the described class ability function as, and are considered to be the given class feature. If it looks like an animal companion and uses the animal companion progression table, why isn't it an animal companion? This for all intents and purposes, functions like an animal companion with extra rules for it being a construct.
I wish I could find the thread I read this on.
Edit: By this logic Cavaliers don't have animal companions they have the 'Mount Class Feature', and therefore are not subject to anything that lists the 'Animal Companion Class Feature' and makes a class irrelevant.
Same goes for Rangers; they have the 'Hunter's Bond Class Feature' so if you select an animal companion, too bad, it only functions 'like' one.

If someone could find an official ruling on that phrasing I would be grateful. Construct Rider was the first place I really looked at that closely, in part because I found it in Hero Lab and they have it implemented as a mount, with none of the Animal Companion features working. And I couldn't find anything to support it being an Animal Companion. I even tried submitting a Bug Report when I noticed it, and they rejected it.

Hero Lab isn't the rules and doesn't make them. Never take anything Hero Lab does as actual rules. You aren't going to find an official ruling, as even the forum posts aren't technically official.
1) This fuctions as the Druids Animal Companion with changes focused on your animal companion being an animal construct.
2) These changes do not change share spells or devotion of an animal companion, and does not say that the animal construct can't have an archetype.
3) Construct Rider came out in the book that update and added stuff to Familiars and Animal Companions, expanding on archetypes. If the Construct Rider wasn't allowed to take an archetype, the book would have said so in no mixed terms.

The Augmented Contruct archetype modified the Handle Animal DC.
This has already been modified in the Contruct Rider mount feature.
They are not compatible.
That’s not a class feature being modified. That is a core mechanic of the Pathfinder game being modified. So as others have said, they are compatible.
