Yes. What's more, the constraints need not be linear. (However do not
expect great speed.)
In[9]:=
Minimize[(-x)*y, {x^2 + y^2 <= 1, x >= 0, y >= 0}, {x, y}]
Out[9]=
{-(1/2), {y -> 1/Sqrt[2], x -> 1/Sqrt[2]}}
Of course this means that the maximum is
In[10]:=
-%[[1]]
Out[10]=
1/2
at
In[11]:=
{x, y} /. %%[[2]]
Out[11]=
{1/Sqrt[2], 1/Sqrt[2]}
