No.

Explanation:

An acute angle means that it is less than 90o (α<90o) or π2 in radians,

If two angles are supplementary, it means that their sum is 180o (x+y=180o) or π in radians.

Now, if two angles are acute, i.e., less than 90o (a<90o and b<90o), their sum must be less than 180o:
a<90o
b<90o
_____
a+b<180o
