Theories such as string theory predict that the space we live in has in fact 10 dimensions, but that the universe measured along these additional dimensions is subatomic in size. As a result, we perceive only the three spatial dimensions that have macroscopic size.

Yes. Lots of scientists think we may have as many as 10 dimensions altogether. But that's a virtually impossible thing for us to imagine.

you should have asked that "can we have less than four dimensions"
There is no upper limit to the number of dimensions.We need atleast four dimensions to specify any event.
Consider some vectors in a plane. Let sum of four vectors(A,B,C and D) along a plane is vector X. So any point on this plane can be defined by four coordinates( one each along each of these four vectors).
so, we can choose as many number of coordinates as required. It all depends on the type of coordinate system we use for our study.

Who says we have 4?
Superstring theory requires a minimum of 11, and some models support up to 28.

So why do we say that we have 3D films, when actually the films we watch in 3D must be 4D as they also have the 4th dimension - Time.

There are theories with infinite dimensions.......

As scientists make new discoveries, they sometimes find thier guesses were wrong, then they make new guesses

that is so it can be more and more we do not know when it will end or maybe not at all
