No, you need to carefully compare the X Chromosome overlap with the shared amount of other autosomal DNA. The catch is that X Chr is relatively small and men have only one X Chr and women - two X Chr. So it makes very difficult to interpret results correctly.
Also as X Chr is investigated alone the provided results may prove very distant (and old!!!) relationship.
I believe that any match with X-DNA below 100cM (almost half of X Chr length) is false positive (i.e. does not have value)
