Yes, chaotic systems can be simulated, and that's the only way to find out what happens with them. The thing one can't do is reduce them to a closed-form function of x and compute their value for any point along their domain. The only thing we can do is inductively figure out the next x from the current x.

With perfect knowledge of the initial conditions and parameters you could simulate the system perfectly, but you'd also need to accumulate zero numerical error along the way. If you don't demand perfection, then in practice you can do pretty well for short times.
