The macro just does text replacement, so the LaTeX exporter
sees naked braces which it escapes as it should.  In fact there seems
to be a bug causing the opening "{" not to be escaped - I have just
fixed that, I hope.

Org-mode buffers are not LaTeX buffers, so braces are seen as just
characters that should appear in print, unless they surround the
arguments of a LaTeX macro.

So you probably could write

   #+LaTeX_HEADER: \def\same#1{#1}
   #+MACRO: rest \same{{\leavevmode \leaders \hrule height 0.7pt 
\hfill} \\}

   Nombre de la escuela de idiomas: {{{rest}}}
   Nombre y apellidos del estudiante: {{{rest}}}


However, I think it is must better and more stable to write:

   #+LaTeX_HEADER: \newcommand{\rest}{{\leavevmode \leaders \hrule  
height 0.7pt\hfill} \\}

   Nombre de la escuela de idiomas: \rest
   Nombre y apellidos del estudiante: \rest

Don't forget that LaTeX is the most powerful macro processor here,
so just use its capabilities.
