dual boot - partitions in windows and ubuntu, can't create more than 4 partitions

I have installed dual boot windows 10 /ubuntu 14.04. As I went through the instructions I saw that by having an EFI bios I can only make 4 partitions max i.e 2 for windows ( primary c drive and a system generated one) and now I have 2 for ubuntu (swap and an ext4 ) is it alright if I make more partitions in windows ?
