Here's a (not completely flippant) answer: yes. At least in the case of Sirius B, and let's be hones, this is the case we care about, a planet that orbits it would be very close to Sirius A too. The distance between Sirius A and Sirius B is always between about 8 AU and 32 AU (1 AU = Sun-Earth distance). Since Sirius A is about 25 times more luminous than the Sun and Sirius B about 50 times dimmer, it is very likely that a planet orbiting Sirius B will receive most of its light/heat from Sirius A, and it would be somewhat comparable to what the Earth and Mars receive from the Sun.
