You’re pretty much there. You just have to return an actual queryset:
{% if A in X.Y.all %}
Test
{% endif %}
UPDATE (based on comment)
That is not possible with template code, you need to do a filter, and the Django templating language doesn’t allow passing parameters to methods. In your view, you can do:
X.objects.filter(Y=A).exists()
And pass the result into the context to be used in the template, but I’m not sure how that fits with your exact needs.
