Yes, but only slightly. The coupling factor between the halves of the resistor will be small, about 0.1, so the reduction compared to a pair of shorter resistors in parallel (without the adjacent arrangement) will be on par, about 10%.
Use a noninductive design.
On a related note, you can equalize it by putting an R+C in parallel, where the R's are equal and C = L / R^2. But this shifts the current from the main resistor to the equalizing resistor at high frequency, so if you need to handle a lot of power at any frequency, yeah no... Can be acceptable for low frequencies with rich harmonics (where the high frequency power is fairly small).
