The bald answer is no view at all. You are not claiming a deduction, so you are paying more tax in Co A.
The relevant company is B. What view might they take if the calculation of profit for B does not include any rental income.
Provided your companies count as small (for EU purposes) http://ec.europa.eu/enterprise/policies/sme/facts-figures-analysis/sme-definition/index_en.htm then they are powerless to impute income into B for transfer pricing purposes.
If you are medium, then they have the power to make you include a notional rent charge between A and B by imposing a transfer pricing adjustment. I guess if you are thinking about marginal relief you are probably small - or even micro.
Presumably the transfer of money to A could be done by interest free loan. Again, provided you are small or smaller then no transfer pricing adjustment could be enforced.
Personally I would be relaxed about the fiduciary duties point where the two companies are under common ownership. Otherwise every time a company made a transfer pricing adjustment then there would be a breach of fiduciary duties.
