It's safe but might be bitter. It means the plant didn't get enough water while growing the cucumber.

From a garden website:

Ocasionally cucumbers form with a hollow interior or 'hollow heart' where the seed cavity should be. Hollow cucumbers are generally a tad bitter and not near as crispy, crunchy and tasty as we would expect. .
