Samuelson joined Rovers on a season-long deal in the summer, but made only four appearances for his temporary employers and started just once.
The Norwegian teenager consequently returned to West Ham earlier this week and, ironically, scored for the Hammers' Under-23s against Blackburn.
According to Coyle, it was his decision to terminate Samuelson's spell, with the player and his family believing him worthy of a more prominent role in the team.
However, the Rovers boss has warned that, given the level of competition in England's second tier, youngsters such as Samuelson can not expect to walk in to his side, regardless of how talented they may be.
"I cut the loan short," Coyle said. "It’s very simple, Martin is a lovely young man, a talented man, but I think there was pressure from his family through to Martin who felt he should he starting every week in our team.
"We had a really good chat about it, I told him very honestly that I can’t guarantee with any player that they are going to start every week.
“It’s a fair fight for them all to be in the team, and with that in mind, I stressed that we only want players at Blackburn Rovers who want to be a part of what we’re doing.
"We both felt that it would be in his interests to go back to West Ham, play some games for the under-23s, which he can do until January, and then kick on from there.
"I do believe that in time Martin will have a very good career, he’s a talented player, but I think there is an element with young players that we operate in probably the fifth or sixth biggest league in Europe so you’re playing against quality players each week.
"So there’s no given, no matter who you are or where you’ve come from, that you will go in to the team."
Blackburn currently have Liam Feeney, Elliott Bennett, Craig Conway and Ben Marshall who can operate in wide areas, although the latter's future is uncertain with his contract up at the end of the campaign and no agreement yet reached.
West Ham left-back Stephen Hendrie remains on loan at Ewood Park.
