Not actually. The conclusion does not fit the test.
The only thing that test indicated was it is safe to assume
the capacitor you have can dissipate the power it was
dissipating in YOUR installation without getting warm to
the touch.
It certainly does not mean it is a good capacitor,
especially in other applications. Stubs are about the lowest
quality capacitor you can use (PC board and window-glass
caps are two others). There are many systems where very poor
components will not fail, but it doesn't mean the component
is good or low loss in other systems.
