No.

1. Sage includes numpy and scipy, which are native Python libraries
that provide most MATLAB functionality to Sage. See, e.g.,
http://www.scipy.org/NumPy_for_Matlab_Users
To include Octave as well would be a huge duplication of
functionality. (Sage also includes GSL -- the Gnu Scientific Library
-- which again would overlap a lot with Octave for functionality.)
2. Octave is very time consuming to build from source, since it is a
large C++ program.
3. Octave as a binary is very easy to install on any modern system, so
there is little point in including it in Sage, since people can easily
just install it. There is a Sage/Octave interface, so you can use
Octave from Sage.
4. Octave is licensed GPLv3, so we can't include it with Sage anyways.
