Can I use a 7mm RUM Redding bushing neck sizing die for the 7 LRM?
No. Rum is a longer cartridge. If you wanted to remove some of the bottom of the die you could get it to work. It might not do a perfectly concentric job as the shoulder diameter of the 7 RUM is .014" larger than the 7 LRM.
A friend has a 7 LRM and he says he got a Hornady bushing die for it.
