Adjust the appropriate left-margin for such lists.
It could be  \leftmargini \leftmarginii \leftmarginiii  etc.
according to the list-nesting depth.

For example:

\noindent
Text before.
{\addtolength{\leftmargini}{50pt}
\begin{enumerate}
\item[(Refl)]%P1
Reflexivity\index{Reflexivity}\index{Binary relation!reflexive}: 
\hspace{21pt} $a
\leq a$.\hfill
\item[(Asym)]%P2
\index{Asym}\index{Binary relation!antisymmetric} Antisymmetry:  $a
\leq b$ and $b \leq a$ imply that $a = b$.
\item[(Trans)]%P3
Transitivity\index{Transitivity}\index{Binary relation!transitive}: 
\hspace{17pt}
$a \leq b$ and $b \leq c$ imply that $a \leq c$.
\item[(Lin)]%P4
Linearity\index{Linearity}:\hspace{29pt} $a \leq b$ or $b \leq a$.
\end{enumerate}}
\noindent
Text after.
