Tensors are said to be multi-linear maps. My question is if tensors can be used to describe non-linear systems? Or if non-linear mappings can be made using tensors?

Can non-linear objects be defined using linear ones?

They certainly can, some famous nonlinear systems that are nonlinear and are described using tensors are General Relativity, where the equations involve the Riemann curvature tensor, and also non-abelian Yang-Mills theory, where you have the field strength tensor. In these theories, the field acts as its own source, so it's in general not true that a linear combination of solutions will be a solution itself.
Think of the case of the one-dimensional derivative. It is a linear map between functions, and can be thought as an operator on a vector space. But that does not mean everything you write with derivatives will be a linear differential equation.
