RC, that isn't a hint.
That is a supposition based on your previous experiences playing D&D. Essentially, the lever itself is what you are considering the hint.
A hint would be something more in the room that would make the PCs think that the lever is more than it is. A pile of dust beside it, a warning sign in orcish (which the PCs may or may not be able to read), a bit of rope tied to the lever left there by previous adventurers.
These are hint. The lever is not a hint.

I suggest that you are using definition (1) and I am using definition (3), above.
When I examine the assumption,
(3) That the DM has given no hints to the PCs that it is dangerous I am assuming that, if enough intimation exists that the PCs know
or should reasonably have known that something is dangerous, perforce this knowledge arises out of "hints".
For example, a bridge over a river "hints" that the river can be crossed. Nothing else is required, because the meaning of the term "bridge" is fairly universal. The implications inherent in an object can be hints. Indeed, all the hints you mentioned are based on the implications inherent in objects. Well, except the warning written in orcish.
Likewise, that a pulling a lever inherently causes something to happen is more than just an inference gained through isolated and special circumstances -- it is inherent in the meaning of the object itself.
