After @CarlWoll's comment:

You can search for undocumented functions by using Names

Names["*`" <> "MatrixConditionNumber" <> "*"]
(* {"LinearAlgebra`Private`MatrixConditionNumber"} *)

Now calling the correct function name

A = {{1., 0.}, {0., 2.}};
LinearAlgebra`Private`MatrixConditionNumber[A]
(* 2. *)
