Nope.

You can't change the color of that indicator.

You could cover it with a different shape, though. (I wouldn't bother.)

Hello,

In Excel 2007 I notice that whenever you add a comment in any cell, the
upper right portion of that cell turns red to indicate a comment has been
added. Is there any way to change the red portion to a different color other
than red. I have different colored cells in my worksheet and the red doesn't
match well with some of them, so it would be nice to be able to change red to
something different.
