That's outside the datasheet spec if I remember right.  They give both a
upper and lower limit on the caps.  Violating either is bad design.

10uF 10V tantalum caps are also relics of a bygone era.  Nowadays we use
ceramics, which are cheaper, more reliable, less sensitive to abuse, and
have better electrical characteristics.
